DOOR-STOP.

Application filed November 13, 1919.

T 0 all whom it may concern:

Be it known that I, JosEPH DANIELE, a citizen of the United States, and a resident of the town of N eedham, in the county of Norfolk and Commonwealth of Massachusetts, have invented certain new and useful Improvements in Door-Stops, of which the following is a full, clear, and exact specification.

It is customary to attach to the base board of a room or to the floor thereof, a rubber-protected knob for receiving the impact of a door when swung wide open. Ordinarily these door stops are provided with a projecting wood-screw which can be screwed into the base-board or the floor by forcibly turning the stop itself. These screws soon work loose, however, so that the door-stops fail to remain in place, and finally will come out at the smallest provocation.

The object of this invention is the effecting of means whereby the door-stops will be retained in place with perfect security and firmness, and can be removed and replaced at will without loosening its hold.

To this end, I provide a metal disk adapted to be attached to the base-board or to the floor, and having a central hole tapped to receive a bolt; the door-stop being given an axially disposed bolt adapted to screw into said hole.

In the drawings forming part of this specification, Figure 1 is a central longitudinal section of a door-stop embodying my improvements, the same being of the kind customarily attached to a base-board. Fig. 2 is a similar section of a door stop of the kind usually attached to the floor, but here illustrated as attached to a wall or base board. Fig. 3 is a face view of the metal attaching disk. Fig. 4 is a section on the line 44 in Fig. 1.

In the drawings, the reference numeral 1 designates the knob or door stop having a stove-bolt 2 axially disposed therein; in Fig. 1, the knob being shown as provided with an axially arranged rubber plug 3, while in Fig. 2 the knob is illustrated as provided with a circumferentially disposed rubber ring 4.

For fastening the bolt 2 firmly in the knob l and 1 the inner end of the knob is chambered, as at 5, for the reception of a nut 6. This nut being firmly turned against the inner surface of the chamber or recess 5, while the bolt head 7 rests against the outer end of the lmob 1*, as in Fig. 2, or

against the inner end of an elongated recess 9, as in Fig. 1, the bolt is solidly clamped in place.

The attaching disk 10 has an internally threaded hole 11, and preferably three screw holes 12 suitably countersunk. This disk is to be fastened to a base board 13 or to the floor at the desired place by means of wood screws 14 having their heads flush with the outer surface of the disk. A hole 15 is also bored through the hole 11 for a suitable dis tance into the base-board or floor to receive the end of the bolt 2.

The bolt 2 is then introduced into the threaded hole 11 and turned by the forcible rotation of the knob until the inner end of the latter is solidly against the disk, the bolt-threads cutting their way into the hole 15. The bolt end is illustrated in the drawings as reaching into the baseboard. l/Vhile this aids in giving rigidity to the knob, through the grip of the wood on the bolt, it is not actually necessary, since the three wood screws bind the disk to the base-board with all necessary firmness, and the bolt confines the knob rigidly to the disk.

Although the disk 10 is shown as attached to the surface of the base board 13, it can as well be set therein, a bit of proper diameter being used for cutting into the wood.

Thus constructed, the door stop is permanently held firmly and immovably, and yet it can easily be removed at any time for repainting or cleaning the wood work, and be returned to be as firmly held as before.

What I claim is:

A door stop comprising a knob having a circular base, a metal disk equal thereto in diameter, having a plurality of screw holes near the periphery of said disk suitably countersunk to receive the heads of the screws to be used therein, said disk having a central hole threaded for the reception of a stove bolt, and a stove bolt passed axially through the knob into engagement with said central hole, whereby said disk can be screwed to a floor or mop-board by wood-screws introduced through said peripheral holes, and the knob can be easily removed therefrom and replaced thereon without loosening its hold thereon.

In testimony that I claim the foregoing invention, I have hereunto set my hand this 1st day of November, 1919.
